Abstract Number: 890 • 2019 ACR/ARP Annual Meeting
Adenosine A2A Receptor Signaling Activates FoxO1 and FoxO3 and Promotes Cartilage Autophagy
Benjamin Friedman¹, Carmen Corciulo ², Cristina Castro-Rivera ² and Bruce Cronstein ², ¹Department of Medicine, Division of Rheumatology NYUSoM, NYC, ²NYU Langone, New York
Background/Purpose: Osteoarthritis (OA) is a debilitating and costly condition caused by loss of articular cartilage secondary to chondrocyte dysfunction. Autophagy is a homeostatic pathway that…

Background/Purpose: Krüppel-like factors (Klfs) are known to play key roles in cell cycle regulation, definition of cell fate and regulation of terminal differentiation. There is…
Abstract Number: 768 • 2013 ACR/ARHP Annual Meeting
Inhibition Of X-Box Binding Protein 1 (XBP1) Is Chondroprotective By Promoting Autophagy and Inhibiting Catabolic Responses

Background/Purpose: Chondrocyte stress responses to biomechanical injury and joint inflammation, and associated changes in differentiation and function, provide a foundation upon which cartilage injury and…
Abstract Number: 44 • 2012 ACR/ARHP Annual Meeting
Inhibition of WNT Signaling Pathway by Sclerostin Maintains Cartilage Homeostasis
Wafa Bouaziz¹, Thomas Funck-Brentano¹, Hilene Lin¹, Eric Hay¹ and Martine Cohen-Solal², ¹INSERM U606 Paris 7 university, Paris, France, ²Rhumatologie A, INSERM U606 Hôpital Lariboisière, Centre Viggo Petersen, Paris, France
Background/Purpose: Cartilage homeostasis is regulated by several mechanisms that influence the anabolic and catabolic tissue balance. Among them, the local activation of Wnt signaling pathway…

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
